Android Performance & Battery

Enable R8 / ProGuard: Enable `minifyEnabled true` and `shrinkResources true` in release build to shrink app size. Optimize Images and Assets: Convert PNGs/JPGs to `.webp` or use vector icons (`VectorDrawable`) whenever possible. Prevent Memory Leaks: Clear observers, listeners, and Context references to avoid crashes or high RAM usage. Efficient Media Loading: Use caching libraries like Coil or Glide to avoid lag during list scrolling (`RecyclerView`/`LazyColumn`). Efficient Battery Usage: Use `WorkManager` for background tasks and avoid keeping CPU awake unnecessarily. Optimize App Launch (Cold Start): Avoid initializing heavy SDKs or blocking operations in Application or Splash Screen.
